pyMAISE.datasets.load_rea()[source]

Load NEACRP C1 rod ejection accident (REA) data. This data consists of 2000 samples of four inputs:

  • rod_worth: reactivity worth of the ejected rod,

  • beta: delayed neutron fraction,

  • h_gap: gap conductance \([W/(m^2\cdot K)]\),

  • gamma_frac: direct heating fraction,

with four outputs:

  • max_power: peak power reached during transient \([\%FP]\),

  • burst_width: Width of power burst \([s]\),

  • max_TF: max fuel centerline temperature \([K]\),

  • avg_Tcool: average coolant outlet temperature \([K]\).

This data set was constructed by perturbing the inputs listed above before REA transient simulated in PARCS.

Returns:

  • data (xarray.DataArray) – Raw rod ejection data.

  • inputs (xarray.DataArray) – Four inputs.

  • outputs (xarray.DataArray) – Four outputs.
